Has anyone ever proved that a racespec head gives you any gains? for the money some people pay i think is silly! for what a few bhp more if that? for like 1k's worth of work on a head lol. Get it ported, strong valve springs, maybe some new cams but gain are the cams going to give you an extra 100bhp i dont think so...I think alot of people throw money at things that arent necessary! shot your money into a good standalone
